Liquefactive Necrosis and Infections Quiz

Liquefactive necrosis is a type of necrosis where dead cells are completely digested, resulting in transformation of the affected tissue into a liquid viscous mass enclosed within a cystic cavity. It is commonly seen in situations of focal bacterial infection (or occasionally fungal infections) and ischemic destruction of brain tissue.

In cases of bacterial infection, microbes stimulate the accumulation of inflammatory cells and the enzymes of the leukocytes digest (liquefy) the tissue, leading to liquefactive necrosis.
